Murder, mob rule, and the making of Lincoln—the true story of three racially motivated murders in Mississippi River towns from 1835 to 1838 that crystalized the worldview of a twenty-something-year-old Abraham Lincoln, inspiring the speech that put him on the national map—“The Lyceum Address”—condemning the violence and lawlessness spreading across the nation.

Lynched: Five white gamblers suspected of aiding a slave insurrection in Vicksburg, Mississippi.

Burned alive: A Black man implicated in the death of a constable in St. Louis, Missouri.

Gunned down: A white abolitionist in Alton, Illinois.

These brutal Mississippi River murders between 1835 and 1838 weren’t just acts of mob violence—they were warnings of a nation on the edge of collapse.

In Murder on the Mississippi, award-winning historian Saladin Ambar unearths the horrors that shaped a young Abraham Lincoln’s worldview, pushing him to find his political voice in one of the earliest and most pivotal speeches of his career—the Lyceum Address—in which we referenced each of these three crimes. Confronted by lawlessness, racial terror, and his own inner demons, Lincoln’s battle was political, deeply personal, and reflective of a nation already at war with itself.

Amid a string of murders that shocked the American frontier, Lincoln faced the devastating loss of his first love, crippling debt, a dangerous brush with illness, and a descent into suicidal despair. Yet from this darkness, he emerged with a renewed purpose—one that would define his leadership in the fight for democracy, human freedom, and the rule of law.

Through gripping storytelling and meticulous research, Murder on the Mississippi sheds new light on Lincoln’s transformation from a struggling young legislator to a man ultimately willing to risk everything to save a nation from itself. The forces that shaped him then—violence, division, and the specter of tyranny—are forces we still reckon with today.

This is not just a story of Abraham Lincoln. It is a story of America.
